public class TIFFTag
extends java.lang.Object
This encapsulates the data stored in a TIFF tag (a single image file directory entry).
That includes the following items:
- identification number, 254 or higher; see the many TAG_xyz constants in
TIFFConstants
for a list of allowed values - type; the allowed types include integer and floating point numbers, Strings etc.;
see the TAG_TYPE_xyz constants in
TIFFConstants
- count; the number of values of the given type that are stored in this tag;
1 or higher
- offset; if count is 1 and the type fits into four bytes, this is the complete
value of this tag; otherwise, it is an offset into the file to the position
that will hold the value(s)
See the TIFF specification manual linked in the description of
TIFFCodec
for more details.

TIFFTag(int id, int type, int count, int offset) - Creates a new tag with the given ID, type, number of objects / primitives stored in it
and offset value.
|
TIFFTag(int id, int type, int count, int offset, Vector vector)
|
int | getCount() - Returns the number of items stored in this tag.
|
int | getElementAsInt(int index) - Returns an item stored in this tag an
int value.
|
int | getId() - Returns the ID of this tag, which may be one of the TAG_xyz constants.
|
Object | getObject(int index) - Returns an object from this tag's Vector of items,
or
null if no such Vector exists.
|
int | getOffset() - Returns the offset value stored in this tag.
|
String | getString() - If this tag has a Vector of items and if the first item
is a String, that String is returned,
null
otherwise.
|
int | getType() - Returns the type of this tag's content as a TAG_TYPE_xyz constant.
|
Vector | getVector() - Returns the Vector encapsulating the items stored in this tag.
|
boolean | isInt() - Returns if the value(s) stored in this tag are of type BYTE, SHORT or
LONG.
|
void | setVector(Vector vector) - If this tag encapsulates more than one item or a single
item that does not fit into four bytes, this Vector
will store all elements in it.

TIFFTag
public TIFFTag(int id,
int type,
int count,
int offset)
Creates a new tag with the given ID, type, number of objects / primitives stored in it
and offset value.
TIFFTag
public TIFFTag(int id,
int type,
int count,
int offset,
Vector vector)
getCount
public int getCount()
Returns the number of items stored in this tag.
getElementAsInt
public int getElementAsInt(int index)
Returns an item stored in this tag an int
value.
index
- zero-based index of the integer item to be returned
getId
public int getId()
Returns the ID of this tag, which may be one of the TAG_xyz constants.
getObject
public Object getObject(int index)
Returns an object from this tag's Vector of items,
or null
if no such Vector exists.
getOffset
public int getOffset()
Returns the offset value stored in this tag.
getString
public String getString()
If this tag has a Vector of items and if the first item
is a String, that String is returned, null
otherwise.
getType
public int getType()
Returns the type of this tag's content as a TAG_TYPE_xyz constant.
getVector
public Vector getVector()
Returns the Vector encapsulating the items stored in this tag.
isInt
public boolean isInt()
Returns if the value(s) stored in this tag are of type BYTE, SHORT or
LONG.
Note that BYTE and SHORT have the same meaning as in Java (one and two bytes
large) while LONG is a 32-bit-value, just like int
in Java.
- if this tag's contains integer values <= 32 bits
setVector
public void setVector(Vector vector)
If this tag encapsulates more than one item or a single
item that does not fit into four bytes, this Vector
will store all elements in it.
The size() method called on that Vector object returns
the same value as getCount().
vector
- the Vector with the items to be encapsulated by this tag
